This is just a note to say how much I appreciate Military Fasteners. Your prices are fair, your shipping is fast and the costs are reasonable. The paper and online catalogs have a huge assortment of products. I also like the fact that there is no minimum order.

Have had nothing but great experiences. If I ever need anything I just email Amelia Fato and she gets me fixed up! Super fast and helpful customer service. 10 out of 10.

Military Fasteners is first on my list for the hard to find items so often associated with Government Projects. Brittany and Michael have always been quick to respond and nothing but professional in every way. I look forward to a continued relationship with Military Fasteners.
